Tip!
pH priority dosing! To protect against overdosing with disinfectants
that contain chlorine, the dosing is only released once the pH value
has entered the control range. Adequately set control range and
dosing performance!

Notice!
As of DSP firmware version ≥ V2.0, different user interfaces are
available.
The top two figures show the DSP firmware version 2S or external
dosing pumps, respectively.
The figure below shows the firmware version GRANUDOS.
Control type: (top left)
Proportional
e.g., peristaltic pumps
2-point (on-off)
e.g., solenoid valves, electrolysis (longer
control times)
Alarm low
lower alarm value
P-range
The dosing works proportionally, i.e., the higher
the difference between setpoint and actual value, the longer
the dosing time (max. 15 seconds).
The smaller the selected control range, the faster the
measuring value will react, which can easily lead to overdosing.
With the 2-point control type, the P-range becomes hysteresis
Setpoint
the device attempts to reach this value
Alarm high
upper alarm value
Dosing time limit
if the control range is not reached within
three times, the set time, the dosing is blocked.
Important:
This fault must be acknowledged manually!
Range
selectable between 0 - 2 mg/l or 0 - 8 mg/l
Cycle
setting cycle time in seconds
